OK, my original engine code was H, but have added intake and now 4v carb. mild cam upgrade and headers.  Heads are 30 over and new forged pistions. When I look up parts do I still check H code or Q or R code  now with upgrades?

Your block is still a 2-bolt block, and your heads are still open chamber with small ports and valves, so it is still an H code.
